PTAL @Peefy @He1pa @zong-zhe.

I am not sure about what to set the Required and Name field for the validation. I think the Name field should be set to the variable name defined in the beginning of the convertSchemaFromJsonSchema function, like Name: name. Please guide me about this.

Edit: I think the new implementation for Name and Required fields should be correct. Please review it.
